2020年6月29日 · While writing the cell notation for a cell, doesn't one have to write the two states in which a species exists in a sequence appropriate to the reaction in which they participate? For example, in the Daniell cell reaction, shouldn't it always be written $\ce{Zn}|\ce{Zn^2+}$, and never, $\ce{Zn^2+}|\ce{Zn}$?

2020年4月14日 · The chapter 1 of the reference 1 describes the Line Notation for Galvanic Cells as follows: A shorthand way of completely describing an electrochemical cell such as Galvanic cell is called line notation. It is a shorthand way of expressing the redox reaction progressing in the electrochemical cell. In this notation:

2018年2月16日 · For example the cell notation you have written above is an example of Metal-Metal Insoluble salt-Soluble anion type electrode. Just look through what reactions happen in them actually. You'll understand. $\endgroup$

2023年1月15日 · If some redox reaction happened with no solid anode or cathode, like all aqueous solutions, something like the unbalanced reaction $$ \ce {MnO4^- (aq) + C2O4^-^2 (aq) -> Mn^+^2 + CO2 (aq)} $$ What would an electrochemical cell notation represent in this situation? Is it even logical to try to get a cell notation? I'm really confused about that ...

2019年7月30日 · Whether it is a spontaneous cell or not, is another question. Now as EdV said, calculate the cell potential as written i.e., consider cadmium half cell as the cathode, and the other silver electrode as the anode. If the Ecell=Ecathode-Eanode turns out to be positive, everything is fine, all that means that the cell, as written, is a spontaneous ...

Hence, you must mention it in your cell notation, between the anode and the cathode. The $\ce{PbSO4}$ formed at the anode is in solid state. Hence, writing it as $\ce{Pb^2+(s)}$ is incorrect, as it is not dissociated into the ions $\ce{Pb^2+}$ and $\ce{SO4^2-}$. With all these corrections, your final, correct cell representation should be:

2020年4月14日 · The chapter 1 of the reference 1 describes the Line Notation for Galvanic Cells as follows: A shorthand way of completely describing an electrochemical cell such as Galvanic cell is called line notation. It is a shorthand way of expressing the redox reaction progressing in the electrochemical cell. In this notation:

2023年11月18日 · Now, for writing the half cell notation for the cells, we are to use platinum as electrode. The question is, should I put it in both the cathode and anode? Because I heard people saying that since the anode already has a solid substance (solid iodine) it's not necessary to add platinum to the anode.

2020年7月4日 · The calomel electrode is not a cell. It can be part of a cell. It is a half-cell. A cell is made of two electrodes, one calomel electrode and another one. The reaction occurring in the calomel electrode is the reaction you present as "overall cell reaction". What you described as "anode half-cell" has nothing to do with electrochemistry.

2024年3月7日 · The cell description is somewhat vague and leaves much to the imagination; it indicates a liquid junction to a solid-state reaction. The Ag-AgCl electrode is reversible to the chloride ion. Its typical use is as a voltage standard used at minimal, hopefully zero, current draw (AKA a good pH meter).
